The module features a built-in solar radiation sensor (includes temperature measurement) and three universal AI/DI inputs. The DI1 input supports anemometer measurement (a device for measuring wind speed).

To measure wind speed and direction, you can use sensors such as the T114 and T115, which are available at various online stores.
Wind speed sensors are available, for example, HERE, where you’ll also find additional information on how to connect them, or HERE.
Wind direction sensors are available HERE, again with technical information, or HERE.
